Ambry Genetics

Dec 28, 2022

The c.575A>C (p.E192A) alteration is located in exon 8 (coding exon 8) of the THOC7 gene. This alteration results from a A to C substitution at nucleotide position 575, causing the glutamic acid (E) at amino acid position 192 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
